I got my hair cut shorter than usual a few weeks ago. I have always washed my hair every other day but , since it's been cut, it's really greasy on day 2. I've stopped using conditioner, in case I was putting too much on and it was contributing to the problem, but that hasn't helped. I don't want to have to wash it every day. Any idea what I can do to stop my hair getting greasy so fast? Thanks!
